Fig. 3. Histogram of hadrosaurid bones from the Liscomb bonebed (Prince Creek Formation) for which at least 10 specimens are known. Size is standardized by the mean of size classes 1 and 2 for each bone. The relative size is adjusted so that the mean size of the size class 1 specimens becomes 1. The hypothesis of normal distribution for all samples, and samples whose relative sizes range 0.88–1.52, are both rejected (p << 0.001). The hypothesis of normal distribution for specimens whose relative size range 0.88–1.12 was not rejected (p = 0.25). Relative sizes of juvenile E. annectens specimens are also shown at the bottom. Note that due to insufficient numbers of corresponding bone types, size class 3 individuals of E. annectens are not shown in the histogram. For raw data, see SOM 3.
